Ontario Provincial Police were en route to assisting a disabled vehicle located on a live westbound lane of the highway just west of Fischer Hallman Road at about 6:27 p.m., according to a media statement.

Before reaching the vehicle, police received additional calls regarding a collision resulting in a serious injury at the same location.

A cube van had driven into a disabled VW Jetta that contained three occupants — a family from Stratford, Ont.

A 38-year-old man, 36-year-old woman and child were transported to Grand River Hospital. The identities of the victims have not yet been released.

At the time of the accident, police believe the man was not inside the Jetta but have not yet confirmed if the woman and infant were in or out of the vehicle, said OPP spokesperson Sgt. Dave Woodford.

The 17-month-old girl was airlifted from Grand River to a hospital in Hamilton where she died.

The woman was also transported to Hamilton and remains in critical, but stable condition. The man suffered minor injuries and remains at Grand River Hospital.

The driver of the van — Hugh John Brake, 53, of Kitchener — was not hurt and was arrested at the scene for impaired driving causing bodily harm.

Brake was charged with dangerous operation of a motor vehicle causing death and causing bodily harm, impaired driving causing death and causing bodily harm, over 80 mgs causing death, obstruct justice and possession of marijuana under 30 grams.

The OPP Traffic Support Team and officers from the Cambridge detachment are continuing the investigation. They are looking for witnesses, including a nurse who was believed to be helping at the scene.

Anyone with information regarding the collision is asked to call Const. M. Upton at 519-654-0150.
